2025 Thomas I. Yamashita Prize Winner: Laura Díaz
Laura Díaz is the co-founder of Partners for Equity and Research at Sonoma State University, a Hispanic Serving Institution, where she trains and supports undergraduate researchers engaging in community-driven environmental justice research. She is also the executive director of the Educator Collective for Environmental Justice (ECEJ) where she leads educator professional development in environmental justice curriculum development and partners with youth and community to drive environmental and climate justice action. She works to empower and support formal and informal educators to imagine and co-create environmental justice curriculum, and she has created environmental justice curriculum and lesson plans that are free for educators to use through the Puente Project and Science Friday. Having grown up in a frontline environmental justice (EJ) community in the San Francisco Bay Area, Laura’s work is centered on combating environmental injustice in partnership with members of her and other frontline communities. Laura supports community-driven research by partnering with community health workers and youth as they explore research questions whose answers can impact their community. ECEJ is committed to decolonize environmental education through student-led and student-driven workshops that flatten typically hierarchical power structures. Laura’s work with youth activists has led to multiple cohorts of students that now pursue action within their own communities. Laura is also a Ph.D. Candidate in Environmental Health Sciences at UC Berkeley where she studies how biomarkers of mitochondrial dysfunction can shed light on the underpinnings between exposure to social and environmental stressors on atopic disease among children in frontline environmental justice communities.
2025 Thomas I. Yamashita Prize Winner: Clara Pérez Medina
Clara Pérez Medina (they/them) is a PhD Candidate in the Department of Geography and a photographer and filmmaker whose work shines a loving light on transformative community work in the world. They blend their academic training with their cinematographic eye for the relationalities of care that make and unmake systems of domination. They grew up as a child of Venezuelan immigrants and moved four times before they graduated high school, instilling in them a deep reverence for the importance of place in identity, community, and liberatory futures and a persistent archival urge to preserve the past. As part of their dissertation work, they create community-based research films that investigate questions of memory, aesthetics, place, and belonging in Oakland and Berkeley, California. Using archival research, oral history, and photographic and film production, they examine dominant and collaboratively produced visual archives with the La Peña Cultural Center and the Archive of Urban Futures, a Black Oakland history research collective led by their mentor Dr. Brandi Summers. They work through film and photographic production as a practice of reciprocity, offering images as archival preservation of place-based memory, promotional material for up-and-coming artists and organizers, and for the material advancement of community projects through visual documentation for their community and funders. Their films also work as public pedagogical tools and organizing resources to draw attention to the visionary solutions put forth by their community partners and to showcase the beauty, rigor, and tenacity of Black and Latinx movement organizations in the Bay Area.
